PROLEYMERIELLA Iridescent Fossil Ammonite with Mother of Pearl Shell, Lower Albian, Cretaceous: Mitsinjo, Madagascar

All of our Fossils are 100% Genuine Specimens and come with a Certificate of Authenticity.

Specimen: Proleymeriella Fossil Ammonite (with natural mother of pearl iridescence)

Age: Lower Albian, Cretaceous Period (approx. 113 to 100.5 million years ago)

Location: Mitsinjo, Madagascar

Scale cube = 1cm: Full sizing please see photo.

About the Fossil:

Proleymeriella is an extinct genus of ammonite, a type of marine mollusc that flourished during the Cretaceous period. This particular specimen originates from Mitsinjo, Madagascar, a region renowned for its beautifully preserved and naturally iridescent ammonites. The stunning mother of pearl shell preservation makes these fossils highly sought after by collectors and natural history enthusiasts.

Ammonites are among the most iconic and recognisable fossils, thanks to their distinct spiral-shaped shells. Despite their resemblance to modern-day nautilus, ammonites are more closely related to octopuses, squid, and cuttlefish. These marine creatures thrived in Earth's oceans between 240 and 65 million years ago before becoming extinct at the end of the Cretaceous period.

The beautiful rainbow-like sheen seen on this Proleymeriella ammonite is a result of the natural preservation of the original aragonite shell layer, creating a mother of pearl (nacreous) effect that shimmers under the light.

Geological Information:

Formation: Mitsinjo deposits, Madagascar

Age: Lower Albian, part of the Early Cretaceous Epoch

Environment: These ammonites lived in warm, shallow seas teeming with marine life, a rich ecosystem now preserved in the fossil record of Madagascar.
